To all whom it may concern.-

Be it known that I, LEoroLD BoTrEN- STEIN, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inCar-Couplings, of which the following is a specification,

reference being had therein to the accom 1 panymg drawings, forming partof the speclfication, in which A Figure 1 is a longitudinal verticalsectional view of my improved coupler on the line I. Iof Fig. 2. Fig. 2is a plan view of the apparatus, showing it in relation to thecari'rame. Fig. 3 is a sectional detail view of the draw-head, showingthe locking-pin raised.

My invention refers to improvements in car-couplcrs and it has for itsobjects to provide a simple, reliable, automatic coupling which may becoupled with "another similar one or with the ordinary coupling-link andis as to the coupling-head oi the type known as the Janney coupler.

The invention also provides for the incorporation with the draw-head ofdraft connections combined with laterally-arrangcd buffers, also ahiding and head ejecting spring incorporated with the draw-head, to-'gether with the improved mechanism for operating the jaw and forproviding for free lateral movement of the draw-head in rounding curves,together with various other details of may hear" at one side or theother.

improvement and construction, as shall be more fully hereinafter setforth.

The device is so constructed as to insure certainty of operation andprevent accidental uncoupling, while meeting the various conditions' andrequirements usual with this class of apparatus. It is entirelyautomatic in its action and designed to avoid all danger of accident orinjury, while materially reducing the shock incident to the coupling ofthe cars.

Referring to the drawings, :2 is the draw head, connected at its backportion with a. tongue or strap 3, secured centrally of the usualbody-bolster 4 midway between the wheels of the truck, and so arrangedto per- 11111; of lateral movement of the draw-head and tongue to theright or left, as indicated in Fig. The draw-head is supported by across-bar 5, extending across umlerneath the car-body, upon which thedraw-head rests by means of an upward and backward L-shaped bracket 6 orother suitable support. Similar .lateral extending supporting-bars 7 7,curved to the radius described by the drawhead, extend across underneaththe car at its front portion, being secured in the butl'erblocks, whichare slidingly mounted in the frames 8 S at each side. These curvedsupporting-bars pass through the upper and lower portion of thedraw-head or engage supporting slotted portions thereof, as shown inFig. 1, sullicient clearance being provided to permit of free movementto the right or left, as will be readily understood. The draw-head isalso further supported by means of a bracket 9, secured underneath thebolster 4, as shown, extending forwardly and pro-- 'vided with a widenedbearing-shoe 10, having terminal ilanges l1 1]. with cushion springs 1212, against which the draw-heml I By these means the draw-head is wellsupported and also maintained in ap n'ox'imate alinemene with the centeroi therar, being still capable of sullicient lateral n'iovement .toprovide for the various positions assumed-in coupling.

13 is the coupling'j aw, pivoted in the drawhead at 14 and. providedwith anopening 15, into which the coupling-pin 16 enters do\\'n wardly,so as to securely hold the jaw in closed position. The/pin 16 may beraised in any suitable manner; but I )reler teem ploythemnstruetionshown in l igs. 1,2. and 3, m which the upper portion oi lhe pm isprovided with rack-toot l 17, engaged by the ITO '. wherein the spring25 and bolt extension 26 are mounted to one side of the center, thus drtw-head, the.lever I9 engaging by a ter- '22 is preferably made in onepiece, as shown a foot-openin -g'ate or door 24, w ich may even with thefloor.

The wrist-pin 21 is also 'curve segment-teeth 18 of alever 19, pivoted at 20 in a bracket extending upwardly from the minalslot an elongated wrist-pin 21 of ac-' ,like bars 7, to correspond withthe radial movement of the draw-head, and crank in F1g, 2, havingsuitable bearings in the 'buffenframes 8. This operating-lever isactuated by a foot-lever 23, extending back- .Wardly beneath theplatform and in register covered by a hinged be laid down lever the backend of lever 19 will be epressed, lifting'coupling-pin 16 to allowfor'outward opening of the jaw employ a spring 25, which in the closedposition of the jaw is under tension and bears forwardly against aterminal bolt 26, having a lip 27 engaging a corresponding slot in thebac (portion of the coupling-jaw, the bolt 26 bein guided inlongitudinal alinement with the raw-head. By this construction when thepin 16 is raised the coupling-j aw will be 1 Shown in Fi show a modifiedconstruction In' Fig. 11

increasing the leverage. The coupling-pin 26 when not in registerwiththe hole 15 0r dinarily rests upon the top of bolt 26 or' upon abackward shelf-like extension 13 of the coupling-jaw, as shown in Fig.9. The couplin aw is also provided with a supplemental loc ing-shoulder28, adapted to engage a corresponding shoulder 29 in the draw-head,against which it will bear and perform its functions if for any reasonpin 14 should become broken or displaced, thereby preventing accidentalpulling out of the couplingj aw in such emergency. It will be seen alsothat the draw-head is recessed or open, as at 30 thus providingsuflicient clearance for the shoulder 28, which may be of any suitablesize and which will be flush with the outer surface of the draw-head.Pivoted at 31 in the upper end of a suitable frame, consisting'princlpally of a hollow pipe-support 32, is a semaphore-signal 33,having a short crankarm 34, attached by a connecting chain or cable 35to a lever 26, secured upon crank 22. By this means when a coupling is oened by operation of an outside crank 23 t e signal will beraised,indicating the condition of the car. Located at each side of thecar-body are the buifenframes 8, which may be of any suitableconstruction, as plates or bars, as shown in Figs. 4. and 5,respectively, which frames are solidly incorporated with the mainframework of the car. Located sub stantially on a level with the lraw-head are the buffers 36, forming the outer portion of sliding blocks37, mounted between the plates 8 and bearing backwardly against stiffbuiier-springs 38, adapted to receive the shock of im act. The bars 7are connected with the b ocks 37 and move backwardlyand forwardly withthem and also by mopendent on the 'other, and together they will work inunison. By this manner of'mounting the draw-head it will be seen thatsufficient rovision is made at all points for ample ackward and forwardand also lateral travel independent of the car-frame, while the pullingpower exertedthrou'gh the coupling-jaw is transmitted to the substantialportions of the framework.

The operation of my invention will'be readily understood from theforegoing descri tion, and it will be-found to provide an ei cientdevicefor the objects in View and to erform its functions eontinuously'inasatisfactory and efficient manner.
